This montane species is probably secure but it is localised and scarce over its small range, which is probably diminishing in extent owing to on-going logging and forest loss; however, its population is not considered to be severely fragmented or restricted to a few locations. It is therefore classified as Near Threatened.
|Previously published Red List assessments:|
|Range Description:||Trichoglossus johnstoniae is endemic to Mindanao, Philippines, where it occurs at Mt Kitanglad, near Lake Lanao, Mt Piapayungan, Mt Apo, Mt Matutum, Lake Parker, Luhan, New Dumangas, T'boli, South Cotabato, Lake Sebu and Mt Malindang (Collar et al. 1999). It was described as uncommon and local, and was formerly considered Vulnerable, but now appears to be moderately common and even locally numerous.|

|Population:||The global population size has apparently not been formally quantified, but the species is described as very uncommon and there are thought to be fewer than 10,000 individuals. On this basis it is placed in the band 2,500-9,999 individuals, equating to 1,667-6,666 mature individuals, rounded here to 1,500-7,000 mature individuals.|
Trend Justification: There are no data on population trends, but the species is suspected to be in decline at a slow to moderate rate, owing to habitat clearance.
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||It inhabits montane forest above c.1,000 m, up to 1,700 m on Mount Malindang and to 2,500 m on Mount Apo (Juniper and Parr 1998). It prefers mossy forest, but also occurs at the forest edge and in degraded and logged areas. Birds in breeding condition have been collected between March and May (Juniper and Parr 1998).|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Generation Length (years):||5.7|
Its preferred habitat is relatively unlikely to be affected by human activities in the medium term, but logging and trapping must remain a concern. As a species of montane areas, it is potentially threatened in the long term by the effects of projected climate change on the distribution and extent of its habitats.
Conservation Actions Underway
CITES Appendix II. Conservation Actions Proposed
Regularly monitor at certain sites throughout its range to determine population trends. Protect significant areas of primary montane forest on Mindanao.
